What is best material to make a vent hood?
 
I have read the threads on ventilation, but I haven't seen a discussion on what is the best material to use to construct a ventilation hood. I assume a vent hood needs to be made of a noncombustible material, but beyond that, what are the pros and cons.

Cement board: easy to find, can cut with a saw, but will be very heavey to hang.

Sheet metal: difficult to do yourself, I can't find anything on how to build yourself. If I go to a metal fabrication place with a design, what material and what thickness (gauge) should I ask for? (with cost in mind).

what other materials have people used? Aluminum siding? Foil backed insulation board?

Thank-you in advance for any comments.

i have a kitchen hood, with a big ass fan on top. my baffles which extend to the bench are cement wallboard. so my hood is made of steel and cement, nothing flammable.

I've seen pictures of someone using a water trough similar to this-

That trough is very similar to what GlassCraft(?) used for their hood in the kit they sold for a while.

That was my old set up, and I don't have a pic sorry. The one I have now is a frame from a metal shelving unit with plexiglass sides, back and front baffle. It captures fumes very well and my exhaust blower is killer! Here is a pic of it.

Posts numbers 10, 30 and 55 is where you can see the plexiglass and the baffle on the top front.

here is how I made my cheap vent hood:

. went to a recycling type place that has lots of discards from home refurb/remodels and found a large SS kitchen hood

. asked a friend to cut SS sheet metal back/sides (1 large piece bent into shape).

. stood the back/sides piece on my table and mounted the hood to the studs at the right height to meet the back/sides

. used aluminum tape to seal the back/sides piece to the hood piece

. had a contractor mount & wire a free exhaust fan (he had leftover from restaurant remodel) and small amount of ducting

. voila
